WINDOW-CLEANING APEARATUS.

Application filed February 9, 1926. Serial No. 87,114=.

This invention relates to a cleaning apparatus particularly adaptedfor use in connection with windows. a

It is primarily aimed to provide a machine which is adaptable to practically all windows and which may be operated from the interior of the building, even when the cleaner proper engages the outer surface of the window panel or panels.

Another object isto' provide a novel'construction wherein the apparatus is adjustable according to the size of dilierent window sills.

A further object is to provide a construction wherein the cleaning device will be urged into engagement with the panel or panels.

Still further it is aimed to provide a novel construction havinginterchanmnble cleaner heads such for instance as a washer and a wiper, together with novel means for connecting the same to a staff or the like.

Various additional objects and advantages will become apparent from a consideration of the description following taken in connection with accompanving drawings illustrating an operative embodiment.

In said drawing Figure 1 is a view illustrating the invention in side elevation and as applied in operative position to a window, the latter and a fragment of the building where it is located being shown in vertical section;

Figure 2 is a plan view of the apparatus;

Figure 3 is a frontelevation of the apparatus; i

Figure 4 is a central vertical longitudinal sectional view through the apparatus;

Figure 5 is an inverted plan view of the apparatus;

Figure 6 is a perspective view particularly showing the under structure or means engaged by the brush staff;

Figures 7 and 8 are respectively detail sectional views taken on line 7-7 and 88 of Figure 2,

Figure 9 is a view in perspective ofthe brush supporting arm,

Figure 10 is a transverse sectional view of the cleaner, v

Figure 11 is a longitudinal sectional view of the wiper, and I Figure 12 is a detail sectional view on a plane indicated by the line l212 of Figure 1.

Referring specifically to the drawings, a stock, bar or bracket is shown as at 10, being for instance of wood, or wood reinforced or otherwise, and adapted for transverse disposition across and to rest on the sill 11 of a window generally shown at 12. This stock 10 is adapted to be fastened to the window sill in any suitable manner and has a cleat 12 secured thereto in any suitable manner including bolts 13 and which has a cutaway portion in which a plurality'of rollers 14 are provided and journaled on said bolts 13, and are adapted to engage the outer side of the window sill 11. To provide for a narrow window sill such as shown in the drawings, supplemental cleat sections 16 are provided to be used in conjunction therewith, said cleats having rollers 17 thereon to func tion similarly to the rollers 14 and journa'led on vertical bolts or the li The sections 16 and cleat 12 are joined by hinges 2O fastened to their outer ends and which hinges are provided with vertical pintles 21 The sections 16 may'thus be swung outwardly from in front oi? the cleat 12 and so as to aline with the ends of the elect, thus when a smaller window is not accommodated, serving as an extended bearing forthe cleat 12 in order to rigidity the structure. hen the sections 16 occupy a position in 'fliront (it the cleat l2" and under the stock or bracket- 10, such sections are securedin that position by means of suitable latches 22 carried by the stock.

-'Disposed transversely otthe bracket 10 is bolt or rod 24 which may be passed selectively through any of a plurality of openings 25 in said bracket, according to the adjustmentdesircd for the parts. A handle is provided at 26 having grips 27 at each end reinforced by means of bolts 28 passed through the end portions of the handle. Bolts 80 also reinforce the handle 26 adja cent the bracket 10 and also form journals for rollers 31 adapted also for engagement with the inner side of the window sill 11 in order that the cleat 12' or cleat sections lGjointlv with the rollers 31 may secure the bracket'in place. To the latter e1ic,'relatively strong contractile coil springs 33 are connected to the handle and at theirother ends .to the rodtor bolt 24-. The movement of the handle 26 under the impulse of springs 38 may be limited as by means of pins or keys 35 engaging in one each of series of openings 37 disposed vertically in the bracket. The pins may be fastened to the bracket against accidental loss as by chains 36.

Adjacent to the outer end oi bracket 10 aslot 38 is provided therethrough and a stall 39 is vertically and loosely movable therein. This stall at its upper end carries any suitable tool or implement for use in connection with the washing, cleaning or polishing ot a window as for instance a brush or mop 40 and a wiper as of chamois at 411.. These instruments all] and ll have a back d2 from which spring lingers if} extend having inturned lugs or terminals ell. The backs l2 also have sockets i5 adapted to detuchably receive the end of an arm to with the lugs ll detach-ably clipping into any selected openings or notches 4:? provided in a row around the arm it; so as to enable the implements 40 and $1 to be placed at any desired position on the arm in. T he engaging end of arm l6 and the socketare preterably tapered as shown The upper end of the stall 39 is preferably square and remorably extends through a square oclret in arm 46, as at i7, and held against accidental detachment by means of a U-shaped latch member 48 engaging through staples it? on arm 46 and an opening 39 in stall 89.

The stall 39 is preferably made in two sections l9 and 50 so that both sections may be used when an extended stall is needed or the section 50 may be removed when a shorter stall is needed. These sections may be de tachably held together by means cl? :1 bolt as at 51 having a thumb nut 52 and by a hook bail 53 pivotally connected to upper section d9. Lower section 49 has an eyelet as at o l to receive said bail Secured adjacent to the lower end of section 50 and held thereto by means (it a bolt 55 and thumb nut 56 is a weight member 5'7, said weight member tending at all times to hold stall 39 in an upright position.

At the outer end of bracket 10 a plate 58 is mounted being hinged thereto by a pair of hinges 59. Plate 58 has a slot (30 therethrough which the stall 39 passes.

Contractile coil springs 61 are fastened to plate 58 and normally tend to swing said plate dowmvardly and the upper end of the stall inwardly into engagement with the window being cleaned. In the slot 38, rollers 63 are provided between which the stall 39 passes, and a roller (i l is also provided in slot (30 to engage stall 39, these rollers serving to guide said stall during its operation by the instrumentalities to be hereinafter described.

.ln order to operate the stud, a handle or grlp is provided at (55, being journaled on one end oi a loop 66 formed on a flexible cord or cable 67 which passes over a guide pulley 68 journaled in slot (39 on a bolt 70 secured through bracket 10, and the other end of the cable 67 has a loop as at T0 that engages in weight member Iii.

In operation, the implements ill and ll-'1 or any others are lllttl'fillilllfltltllIll used. that at being used tor washing and cleaning :1 window panel while that at -l-l is principah ly used for wiping and drying the Wllltll')\ panel subsequent to use ol' the implement l0. ll'hcn a long stall 35) is dos Jud hot h sections ll) and 50 are used but when 1: short one i1: preferred. section no is delucluid and the bolt 55 applied to opening ill and the cable ('37 and weight a? appropriately con nected.

The hand of the operator not cngag 1g the grip 27 engages the OlQllllIllt or grip on moving it to and :lro. thereby rerlir-ally or substantially vertically reciprocuting the stall and cleaning element. The upward movement o t course is ugi aiust the tendency ol. weight member 57 to hold the stall in its lowerm -;t position, and hence when the grip ll? re" leased, the weight member will return the stall and implement to raid, lo 'eriuost posh i. Incidental to this rci ical rcciprma lion, the operator may more the ln'aclzel' lll loim itudinally with respect to the window sill so that the entire surface ot the panel or panels may he oll'ectircly clcaucd.

Various channels may be re1-orlcd to provided they fall within the spirit and scope of the invention as claimed.
